Abstract In this paper, we propose a method to investigate the AC corrosion on the basis of the effect of electric field combination with that of electrochemistry. Under the effect of strong yet swiftly changing electric field, the electrochemical process of corrosion has changed essentially, and the intensity of electric field is an important physical parameter. After measurement and analysis of the interfering voltage, potential gradient, the point current density, the weight-loss increases with average current density, and the depth of penetration increases with the interfering voltage. Based on experimental results the authors have proposed safety limits of voltage on prevention of corrosion.
